On Wednesday, Dunkin’ Donuts (DNKN) announced that it will introduce gluten-free cinnamon-sugar donuts and blueberry muffins later this year. The move is meant to boost menu options for customers facing dietary restrictions, CNN notes.

A protein found in rye, barley and wheat, gluten can produce uncomfortable reactions in people who are sensitive to it. Sufferers of celiac disease can experience severe reactions to even small amounts of gluten.

Dunkin’ Donuts joins a number of other restaurant chains that offer gluten-free menu items, including Chipotle Mexican Grill (CMG) and Domino’s Pizza (DPZ).
